2) inclined angle carrying a brick on the head is more than 60 or be less than 45 degrees
3) inclined ash carrying a brick on the head is seamed not close-grained
7, concrete and body of build by laying bricks or stones hand over difference of the processing that hang a net
The blemish that hang a net reflects basically reflect for the following each respects:
1) body of build by laying bricks or stones and structure hand over a face to did not hang a net
2) body of build by laying bricks or stones and structure hang a net to secure unreasonable
3) body of build by laying bricks or stones and structural presence discretion are poor
4) place of horn of yin and yang uses galvanization steel wire to secure
8, cop opens groove to secure difference
Cop opens groove to secure difference to basically reflect in the following respects:
1) open groove to destroy wall system
2) deepness opening slot is insufficient, seal a ply inadequacy
3) single-track canal is not had fixed
4) much group line is in charge of " article " the word is fixed
9, cop chamfer does not seal a direct stucco
10, body of agglomeration build by laying bricks or stones waters time
Fired brick waters to basically reflect in the following respects:
1) add mortar moisture content, fired brick does not water,
2) water the quantity is too little, moisture content of form of build by laying bricks or stones is not saturated,
3) water ahead of schedule time is shorter, appearance of substance of build by laying bricks or stones has bright water
11, craze of bigger casing periphery
Casing periphery craze basically reflects in the following respects:
1) brick of condole of reinforcing steel bar of body of casing upside build by laying bricks or stones, body of build by laying bricks or stones sinks bring about craze
2) casing mouth of a cave not obligate, the cut after body of build by laying bricks or stones is finished is brought about destroy body of build by laying bricks or stones or mortar cannot fill is entered
3) casing obligate mouth of a cave is too big, body of build by laying bricks or stones is sealed optional
4) existence of step of group of system of casing back build by laying bricks or stones seams baste foolishly
12, heavy panel of plasterer monolayer ply
Stucco of plasterer mortar monolayer exceeds 1cm, because time coagulates at the beginning of mortar longer, plaster initial stage brings about felt force extremely easily to be able to 't offset self-prossessed, bring about stream object craze, empty beat
13, plasterer mortar uses mortar king
Plasterer mortar uses mortar king, replace gesso (slaked lime) , use 1:1: 6Mixture mortar deserves to compare, because mortar king itself does not increase strength, easy bring about mortar strength inadequacy to bring about craze
14, face of plasterer of section of dry tall warm season not conserve
15, the plasterer face that finish opens groove to wear a canal
16, 2 craze after empty beat is repaired, empty beat
Repair empty beat blemish 2 times to basically be the following respects:
1, empty swell place not cut hits authentic to bring about circumjacent sky to rouse directly
2, face of authentic of get rid of and cut section did not clear clean reach aspersion is wet
3, empty beat face was not divided second repair
4, after repairing before coagulating first not laminating conserve
Sum up: Earth builds metope craze cause of formation to include the following
1, steel model construction uses useless engine oil to wait as film agent
2, concrete surface did not pull hair or play wool quality difference
3, build by laying bricks or stones builds the wall on the brick
4, body of build by laying bricks or stones is seamed foolishly
5, blemish of mouth of a cave of body of build by laying bricks or stones
6, blemish of inclined construction carrying a brick on the head
7, concrete and body of build by laying bricks or stones hand over difference of the processing that hang a net
8, cop opens groove to secure poor quality difference
9, cop chamfer does not seal a direct stucco
10, body of agglomeration build by laying bricks or stones waters time is unreasonable
11, craze of periphery of bigger casing box
12, heavy panel of plasterer monolayer ply
13, plasterer mortar uses mortar king
14, face of plasterer of section of dry tall warm season not conserve
15, the plasterer face that finish opens groove to wear a canal
16, 2 craze after empty beat is repaired, empty beat
